Clemens, who last pitched in the majors in 2007 with the New York Yankees, is scheduled to make another start for the independent league team Friday night. And it might be even more special than a return to the majors.

The Houston Chronicle reports Koby requested and was granted his release from the Toronto Blue Jays organization on Tuesday, with the goal of completing an all-Clemens battery with his father Friday.

Clemens tossed 3 1/3 scoreless innings for the Skeeters on Aug. 25, fueling speculation that he would try to pitch for the Houston Astros at some point in the final month of the regular season. Astros owner Jim Crane has admitted he is interested in the idea, and Astros general manager Jeff Luhnow says the team will scout Clemens again Friday.

"We're going to make sure we're prepared," Luhnow told MLB.com. "If we have the information from a baseball perspective to see what he looks like, we're going to have a scout there. It's an easy game for us to cover."

In his 24-season major league career, Clemens went 354-184 with a 3.12 ERA. He finished third all-time in strikeouts with 4,672, won seven Cy Young Awards and was the 1986 AL MVP.
